Does ITZ influence moisture transport in concrete?

July 24, 2022
Author(s)
Laura E. Dalton, Jacob LaManna, Scott Jones, Mohammad Pour-Ghaz
The contributions of the interfacial transition zone (ITZ) to mass transport in cement-based materials remain ambiguous and disputed. In this study, the neutron and X-ray tomography (NeXT) system is used to capture unsaturated moisture flow in a concrete

Design of a 3000 pixel transition-edge sensor x-ray spectrometer for microcircuit tomography

August 1, 2021

Paul Szypryt, Douglas Bennett, William J. Boone, Amber L. Dagel, G Dalton, William Doriese, Malcolm Durkin, Joseph Fowler, Edward Garboczi, Jonathon D. Gard, Gene Hilton, Jozsef Imrek, E S. Jimenez, Vincent Y. Kotsubo, K Larson, Zachary H. Levine, John Mates, D McArthur, Kelsey Morgan, Nathan J. Nakamura, Galen O'Neil, Nathan Ortiz, Christine G. Pappas, Carl Reintsema, Dan Schmidt, Daniel Swetz, K R. Thompson, Joel Ullom, C Walker, Joel C. Weber, Abigail Wessels, J W. Wheeler
Feature sizes in integrated circuits have decreased substantially over time, and it has become increasingly difficult to three-dimensionally image these complex circuits after fabrication. This can be important for process development, defect analysis, and

An Assistive Learning Workflow on Annotating Images for Object Detection

December 9, 2019
Author(s)
Vivian W. Wong, Max K. Ferguson, Kincho H. Law, Yung-Tsun Lee
We present an end-to-end workflow to generate annotated image datasets for object detection. With this workflow, which we call assistive learning, we are able to reduce manual annotation time on two experimental datasets by 79.4% and 83.1%. The

Thermodynamic properties of 1-phenylnaphthalene and 2-phenylnaphthalene

January 18, 2014
Author(s)
Robert D. Chirico, Andrei F. Kazakov, William V. Steele
Measurements leading to the calculation of thermodynamic properties in the ideal-gas state for 1- phenylnaphthalene (Chemical Abstracts registry number [605-02-7]) and 2-phenylnaphthalene (Chemical Abstracts registry number [612-94-2]) are reported

Porosity of Additive Manufacturing Parts for Process Monitoring

July 26, 2013
Author(s)
John A. Slotwinski, Edward J. Garboczi
Some metal additive manufacturing processes can produce parts with internal porosity, either intentionally (with careful selection of the process parameters) or unintentionally (if the process is not well understood.) Material porosity is undesirable for

Automated Multiprobe Microassembly using Vision Feedback

October 5, 2012
Author(s)
John D. Wason, John T. Wen, Jason J. Gorman, Nicholas Dagalakis
This paper describes the algorithm development and experimental results of a vision-guided multi-probe microassembly system. The key focus is to develop the capabilities required for the construction of three dimensional (3D) structures using only planar

Comparison of Measured and Predicted Tracer Gas Concentrations in a Townhouse

August 1, 2003
Author(s)
Steven J. Emmerich, Steven J. Nabinger, A Gupte, Cynthia H. Reed, L A. Wallace
To further validate the use of the multizone airflow and contaminant model, CONTAMW, experiments were performed in an occupied 3-story townhouse in Reston, VA. A tracer gas, sulfur hexaflouride (SF6), was manually injected within one room of the house and

Validation of CONTAMW Predictions for Tracer Gas in a Townhouse

August 1, 2003
Author(s)
Steven J. Emmerich, Steven J. Nabinger, A Gupte, Cynthia H. Reed
To provide additional validation data for the multizone airflow and contaminant model, CONTAMW, experiments were performed in an occupied 3-story townhouse in Reston, VA. A tracer gas, sulfur hexaflouride (SF 6), was manually injected within one room of
